Remember your history, most lynch mobs were Democrats. Lincoln and MLK were Republicans. Their assassins were Democrats.
Yes, but dems did get clever in the 60s. The violent white labor racists, the exploitative business racists, and the "White Man's burden" patronizing racists all came together with a welfare system that made all of them happy. Blacks were pulled out of the workforce which inflated wages for white unionists. Black folks were used as the pass through for Welfare check money and other subsidies for racist democrat crony capitalists and the patronizing racists got more people to feel superior to. I don't believe either MLK or Frederick Douglass would approve.
